Interesting comparisons, Richard! I'm glad you took the time to document their histories and show side-by-side comparisons of the styles/sizes. It makes it very easy to identify the makers.

The two clan badges I wear on my Balmorals are very different from each other. I couldn't remember who made them, as I've had them for over a decade. Clearly, one is Gaelic Themes and the other is Art Pewter Silver. I much prefer the finer or less "chunky" look of the Art Pewter Silver badge.
